This prevents the compiler from issuing a spurious error in a convoluted case where a child generic package declared in an enclosing parent generic package, which contains a second child generic package, contains an inlined subprogram and the second child generic package contains an instantiation of the first, and the enclosing parent generic package is instantiated with inlining across units enabled (-gnatn[12]). The problem is that the compiler attempts to instantiate the body of the first child generic package in the context of the enclosing parent generic package, instead of doing it in the context of the instantiation of the parent generic package, because of the presence of the inlined subprogram. 2019-08-13 Eric Botcazou <ebotcazou@adacore.com> gcc/ada/ * exp_ch6.adb (Expand_Call_Helper): If back-end inlining is enabled, also instantiate the body of a generic unit containing a subprogram subject to aspect/pragma Inline_Always at optimization level zero. * sem_ch12.adb (Might_Inline_Subp): Minor tweak. (Analyze_Package_Instantiation): Do not instantiate the package body because of inlining considerations if the instantiation is done in a generic unit. Move around similar condition involving the main unit. Add test on Back_End_Inlining to processing for front-end inlining. gcc/testsuite/ * gnat.dg/generic_inst8.adb, gnat.dg/generic_inst8.ads, gnat.dg/generic_inst8_g.adb, gnat.dg/generic_inst8_g.ads: New testcase.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
